      ShardingSphere has switched to ANTLR parser which a little slower than before since 3.1.0.
But consuming 3s in parsing is unexpected. If you have doubt, please open another issue to discuss it. BTW, there’s cache mechanism, if you use prepared statement, the parsing time of next query will be 0.

OK, I created another issue:#1738
